DOOR FASTENER.

Application filed August 11,1923.

T 0 all whom it may concern.

Be it known that I, CARL HOFFMAN, a citizen of the United States,residing at Allentown, in the county of Lehigh and State ofPennsylvania, have invented certain new and useful Improvements in DoorFasteners; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. I

This invention relates to door fasteners and particularly to a fasteneradapted for looking a door in either closed or partially open position.

An object of this invention is to provide a latch and keeper for a'doorand jamb to lock the door in closed position and to secure an operatingmeans to the latch adapted for locking cooperation with the keeper tofasten the door in partially open position.

Another object of the invention is to pro vide a latch and keeper for adoorand j aml to lock the door in closed position and an operatingmember for the latch adapted for association with an auxiliary latchingmeans carried by the keeper for fastening the door in partially openposition.

A further object of this invention is to provide a latch rotatablymounted on a jamb adapted for engagement with a keeper plate secured toa door, the latch being provided with an arm pivoted thereto acting as ahandle for operating the latch and being further provided with anauxiliary keeper adapted for association with a pivoted member carriedby the keeper plate which is adapted to secure the auxiliary keeper tosaid plate for locking the door in partially open position.

The invention includes further objects and novel details of constructionspecifically pointed out in the following description and zlaims andshown in the accompanying drawings in which Figure 1 is a perspectiveview of the invention applied to a door and j amb with the partspositioned to fasten the door in partially open position. Figure 2 is apersective view showing the door in closed position and the parts beingdisengaged sothat the door may be locked in closed position, and Figure3 shows an elevation of the door and jamb with the parts positioned tolock the door in closed position.

1 indicates the door adapted to close in the jamb 2 which is providedwith a plate 3 Serial No. 656,851.

supporting a rotatable spindl 4 having a latch 5 formed therewith andprojecting laterally therefrom. An elongated rod-like member 6 has oneend pivotally connected with the spindle 4L indicated at 7 and the otherend provided with an auxiliary keeper 8 projecting laterally therefromand provided with an opening at 9.

A keeper plate 10 is secured to the inner face of the door and isadapted to cooperate with the latch 5 to hold the door in closedposition and take the wear of said latch. The keeper plate 10 isprovided with a stud 11 to which is pivotally secured a. guiding andauxiliary locking member 12 which is adapted for insertion in theopening of auxiliary keeper 8 and for guiding said keeper in the openingmovement of the door to a position shown in Figure 1 after which themei'nber 12 is moved on its pivot to lie against the door as shown inFigure 1 for locking the door in partially open position and against afurther opening or closingmovement. In order to insure retention of themember 12 in locked relation with the auxiliary keeper a catch 13 isrotatably mounted in the keeper plate 10 and is adapted to engage themember 12 and hold the same in locking position.

Figure 2 shows the door with the parts in position as it is being closedfrom the partially open position in Figure 1 the rod 152 guiding thekeeper 8 in the closing movement of the door. From this position the rod12 is disengaged from the keeper 8 and is swung back against the doorand secured in this position by the catch 18 as shown in Figure 3 andthe elongated member 6 is used as a handle for operating the catch 5 torotate the same and bring it in engagement with the keeper plate 10 forlocking the door in closed position. The progression from closedposition, as shown in Figure 2, to the partially open position, as shownin Figure 1, in which the rod 12 interlocked with the keeper 8 has beenmoved on its pivot and secured against the door by the catch looking thekeeper 8 therewith and holding the door in partially open position isapparent.

It is to be noted that the parts illustrated in the drawing and abovedescribed are adapted for use with a door which opens inwardly the partsbeing shown secured to the inner face of the door and jamb.

I claim as my invention:

1. A door fastener including a door carried element and a jamb carriedelement, one of said elements being movable for engaging the other tolock the door in closed position, operating means for the movableelement, said operating means be'inga dapted for engagement with theother element, and positive independently operable means for lockingsaid operating means in engagement with the other element for lockingthe door in partially opened position.

2. A door fastener including a keeper, and a latch, one mounted on thedoor and the other on the jamb, and adapted for cooperation to lock thedoor in closed position, and an elongated member having pivotalconnection with the latch for operating the same to engage or disengageit from the -keeper, and latch means carried with the keeper forcooperating with the free-end of the member for fastening the door inpartially open position.

3. A door fastener including a keeper and a latch, one mounted on thedoor and the other on the jamb and adapted for cooperation to look thedoor in closed position, an elongated member pivotally connected withthe latch, means carried with the keeper having. a sliding connectionwith the member from the closed position of the door to apartially openposition-thereof, and locking means associated with the keeper forlooking the membertherewith to fasten the door ill a partially openposition.

plate mounted on the door, a latch rotata 1e on the jamb adapted forengagement with thekeeper plate to lock the door in closed position; anelongated member havlngone end pivotally connected with the latchadapted for operating saidlatoh and provided at the other end with anauxiliary keeper, an auxiliary latching and guiding member pivotallymounted on the keeper plate adapted for sliding cooperation with theauxiliary keeper for guiding the samein opening movement of the door andfbrinterlocking therewith to hold the door in partially open position,and a catch mounted on the keeper plate adapted for holding theauxiliary latching member in looking position.

In testimony whereof I have-signed this specification, a

- CARL HOFFMAN.
